Circuit diagrams or schematic diagrams show electrical connections of wires or conductors by using a node as shown in the image below. Understanding which components are which on a schematic is more than half the battle towards comprehending it.

How to read a schematic wiring diagram. Schematic nets tell you how components are wired together in a circuit. These show how the components are connected. If you want to build the circuit you only need to get the components specified then connect them as shown in the circuit diagram. This instructable will show you exactly how to read all those confusing circuit diagrams and then how to assemble the circuits on a breadboard. For all the electronics hobbyist wannabes this is a must read instructable. Knowing how to read circuits is a very useful skill that will help you out all the time.
Wiring diagrams or layouts illustrate the physical connections or wiring between components. Each of the lines are wires. Reading schematics is actually pretty easy. Nets nodes and labels. To read electrical schematics the fundamental electrical schematic symbols should be understood. To read it identify the circuit in question and starting at its power source follow it to ground.
Especially if you start messing around with building little electronics projects. To read a wiring diagram first you have to know what fundamental elements are included in a wiring diagram and which pictorial symbols are used to represent them. Parts that are shown broken down into their sub components for the schematic retain their complete package format for the wiring diagram. Use the legend to understand what each symbol on the circuit means. Recognizing electrical schematic symbols here are some of the standard and baisc symbols for various components for electrical schematics. The common elements in a wiring diagram are ground power supply wire and connection output devices switches resistors logic gate lights etc.
They are crucial to the assembly of the circuit or system. Recognize wiring diagram symbols. A car wiring diagram is a map. Below is a list of color codes commonly used in wire diagrams to portray wire color and their purposes. A node is simply a filled circle or dot. The power supply is shown at the top and the earth at the bottom to facilitate understanding of the current flow.
When three or more lines touch each other or cross each other and a node is placed at the intersection this represents the lines or wires being electrically connected at that point. A 4 how to read the wiring diagrams how to read circuit diagrams how to read circuit diagrams the circuit of each system from fuse or fusible link to earth is shown. Now all that remains is identifying how all of the symbols are connected together. Then well talk about how those symbols are connected on the schematics. Im an auto technician for over twenty years ive always loved the electrical side of auto repair. Most wire diagrams will have a legend or key just like a road map explaining wire color codes or any other special information needed to read the diagram.
